13" x 13" Lock-Top II Chimney Cap and Damper

Traditional dampers are located in the "throat" of a fireplace. They are made of cast-iron and are housed in a low-tech frame work. These cast-iron dampers do not seal well—they have a leaky, rough, metal-to-metal seal. Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!

Lock-Top Energy Saving Dampers seal tightly to save you money. Lock-Top's rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should be...in your home. Lock-Top mounts on top of your chimney to keep out animals and rain, and easily operates from inside your firebox, sealing tight every time you close it—eliminating any draft.

Stainless Steel is the most popular cap material due to its longevity and flexibility of fuel being burned. Meaning if you have a wood fireplace and switch to gas logs, the Stainless Steel Cap can handle the change with no concern. These Stainless Steel Caps are backed by a Lifetime Warranty and won't rust, so will remain looking beautiful for many years to come.
